Application tiled February 28, 1917.

-To all 'whom t may concern:

Be it known that I, HENRY H. Hoces,V :i citizen of the United States ofAmerica, residing at lfVest Savannah.y Chatham county, Georgia, UnitedStates of America, have invented certain new and useful Improvements inOil-Burners;- and I do herebyA1 declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame', reterence being had to the accompanying drawings.l and to lettersor figures of reference marked thereon, which form a part ot thisspecification.

'My invention relates to oil burners in which the oil is projected fromthe burner by means of steam. and more particularly to that type ot'burner in -which the steam projects the oil over a platform at thedischarge end of the burner to obtain subdivision Ior spraying of theoil into a furnace chamber or other chamber to be heated.

Referring to the accompanying drawings,- in which like pa rts aresimilar-hY desig- Figure 1 a. plan view of a burner ein bodving myinvention.

Fig. a side. view thereof.

Fig. 3 is a longitudinal section. on line 3-3 ot' Fig. l.

Fig. et is an end view.

Fig. 5 is a cross section on line. of Fig. 1.

Fig. is a cross-section 0n line (--U of Fig. 1. f

Fig. 7 is a cross section illustrating a. modification.

Conveniently the burner is made in three parts, comprising a steamchamber 1. having a Steam inlet Q and an oil' chamber 3 provided with anoil Vinlet. Jr adjacent to which is a clean out, closed by a. plug Thetwo chambers are separated from one :mother by an interposed plate (3,and bolted or screwtul together by screwsl 'Both chambers discharge ontothev platform. the steam chamber through a port S la rger than theIdischarge port 9 of the oil chamber.

Such a. construction of the body of the loin-nel.` is known; myinvention consists'in a particular construction ot' the platform.

The object of in v invention is to better distribute the oil throughoutthe furnace chamber to obtain a bett-er heating of the chamber and atthe same time obtain a bet- Specicaton of Letters Patent.

ter combustion, thereby materially1 increasing the etliciency of theburner.

.lt will be observed thattheplatform is curved at its discharge :endltljthereby el?r tee-ting 4the discharge from the several sprayingelements'terminating at this end at (flitl'erent points, 'as will behereinafter explained.

The platforu'ralio widens from an apron 9 of the oil discharge orificeto the curved or seniieirculai.- end 10%' The 'apron 9xi is parallel tothe plate 6 to Iprovide.- a longi; tudinally directed o il port 9. A

Along the middle of the. platform I provide a. groove l1,preferablyhaving an upward incline 4from theoil discharge port 9 to themiddle ofthe curved 'portiomas shown. This groove 11: is preferablydeeper and wider than thegrooves 1i). that are arranged one at eachside' of said groove T1. The grooves 1&2 are preferably inclined to agreater degree than cthe groove 11, so that they terminate at the/curvedend of the platt'orm at a higher level, Fig. 4. 'l i The grooves 11 and12`are rect-angular, or substantially so, in cross sectiomand locatedbetween them are channels "13 terminating in upwardly directed lips-X14.These chunnels 13 have substantially the same inclination as thechannels 1 2, but .differ from them iu being eur-ved incross-section.Their side walls 13 at the port 9' are on the Sallie level as the apron9".

The outer sides of grooves. 1 9 are formed bv the beveled 4sides l5 ofthe platt' 11n. These sides project above the other elements ot theplatform and havebeveled t'aces 16.

The operation is as follows:

Steam and oil are supplied'through the vespective inlets i2 Aand '4 tothe respective chambers 1 and 3. asis customary with this tvpc ofburner. The oil discharges from the oil port .l over thc apron El ontothe platform and is drivcn over the platform by the steam issuing fromthe .steam port 4 'lhc middle. .wider and deeper groove 11 carries thelargest quantity of oil lo thc most cxtreme point of the curved cnil l()of the burner at the lowest level. Other streams arc carried anddirectcdb v the grooves if? at an angle to thc Stream in groove 1l.` to thcfront of the bur-ucr. (-)il' also passes alongr the grooves li'alulisprojectml upward and awav from theplarform b v 4striking thc inelincl-lwallsI ot' lhc upwardly lirected lips yl-L at the ends ot' .saidgrooves.

'and 121 as somewhat the shape of a quadrant of a sphere, and thusiswell suited for use in the tire boxes vof locomotives and other engmes.In Fig. Y I have shown the grooves' l1 greater quantity` of oil` andcarry a very much larger quantity. 'to the end of the platform, so thatthe streams issuing from the platform will be projected farther from theplatform -before being broken up by the,

steam. The undercnts prevent too large a part of the oil from beingspreadv from them laterally over the platform by 'the high pressuresteam. r I

The `sides of the platform are also made higher than-in Figs. 1-G, andinstead of having plain beveled oil-'dispensing surfaces, they are shownslightlyv cnrvedas at 1G, so as to present a surface of beveled type.but somewhat steeper .than the surface 16. Such a structure ispreferable where. the tire box is long, vas the flame produced by siicha dburner is xnoreelonga'ted.
